Funny that you mention it. I was thinking about doing this in our spare time as well. We go to a lot of car shows where our compressors are used for air suspension and we give away T-shirt from time to time...So why not make a pneumatic T-shirt cannon?
Here's the one that I wanted to make.

If you decide to move forward with the project, please upload a video for us to see as we at VIAIR would love to see the final product.
We've been talking about creating a mobile pack using a small 12v motorcycle battery or two 6v batteries wired in series to reduce weight, strapped to a backpack with our 250C IG series so that we could carry it around with our t-shirt cannon. Though I have to be honest...i don't know if this idea will ever come to fruition.
